SLQ Water-cooled Air Cooler

In positive pressure conveying engineering, the compressed gas often accompanies high temperatures during its generation. The outlet gas temperature of common Roots blowers can reach 60°C to 90°C. Using such high-temperature gas directly for conveying food materials can cause negative effects such as material denaturation and moisture loss. The SLQ series water-cooled air cooler can cool the air inside the Roots blower to below 38°C, thereby reducing or even eliminating these effects, reducing the defect rate, and improving product quality.

Product Description

　　 1. Product Introduction
　　In positive pressure conveying engineering, because compressed gas is often accompanied by high temperatures during its generation, the outlet gas temperature of common Roots blowers can reach 60°C to 90°C. Using such high-temperature gas directly to convey food materials can cause material denaturation, moisture loss, and other negative effects; the SLQ series water-cooled air cooler can cool the air inside the Roots blower to below 38°C, thereby reducing or even eliminating these effects, reducing defect rates, and improving product quality.
　　The SLQ series air cooler is a high-temperature and high-pressure gas cooling device developed by our company through digesting and absorbing advanced foreign technology. During use, it uses a water pump to generate driving force, driving the cooling water to flow back and forth in the heat exchanger and circulation system, thereby achieving the effect of cooling high-temperature and high-pressure gas.
　　 2. Performance Features
　　1. The parts in contact with water are made of 304 stainless steel, durable and long-lasting.
　　2. Inside the radiator, the water is under negative pressure while the process gas is under positive pressure, fundamentally preventing the possibility of water contacting the material.
　　3. Compact structure with flexible and diverse installation methods.
　　4. High heat transfer efficiency, rapid cooling, stable operating conditions after reaching the set temperature.
　　5. The outlet gas temperature can be freely set, equipped with a programmable controller and human-machine interface, enabling automated control and unattended operation.
